Benefits of technology

[0021]What we do by the methods of this patent is to structure the airflow within a space so every person breathes “clean” air from a pool above their heads, and what they breathe out is moved to the “dirty” space below their heads. The flow past their heads is fast enough that normal exhalations cannot reach the head of the person next to them. In effect, the methods of this patent reduce [p] and [fu] for airborne transmission within businesses to near zero by avoiding mixing. This is critical. Downward flow is preferable, since exh...

Problems solved by technology

This results in air conditioning costs that are too high, since the total air flow required is much higher than that required by n...

Embodiment Construction

[0035]In the method contemplated by this invention each patron (4) breathes in “clean” air that comes down from the pool (1). The potentially contaminated air they exhale is entrained by the flow, taking it below their heads and thus preventing re-breathing of the possible contaminants by other patrons. The diffuser acts to evenly distribute the air from the clean pool over the patron space, and to prevent any eddies that would cause one patron to breathe unfiltered air exhaled by another patron. It can be as simple as a cloth screen between the pool and patron space. Even adequate distance between the ports that bring air into the clean pool and the patron space can act as the diffuser. Note that diffusers in standard ventilation practice are usually designed to enhance mixing—the opposite of what we want to do here! Even without any recirculation and using the ASHRAE “people outdoor air rate”, each patron in this airflow will be breathing air that will be cleaner than that provide...

Abstract

This patent presents a method, and some devices based on the method, to achieve near zero air based transmission of disease within a business, while still allowing people to approach each other closer than arms length touching distance. This can be achieved with rapidly deployable portable units. It also presents a simple method to test whether the airflow structure requirements of the system have been met, and to adjust it if not.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This patent application claims the benefit of the filing date of a previously filed provisional U.S. application 63 / 199,601STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableBACKGROUND OF THE INVENTION[0003]This invention is related to the class of systems and devices to suppress transmission where a disease is transmitted primarily over air. Related areas include air handling systems, air purifiers, and air conditioning systems. Other related areas are laminar flow workbenches, laminar flow hoods, and laminar flow clean rooms.[0004]The Covid-19 crisis has demonstrated the need for a rapidly deployable system that can effectively suppress transmission of airborne disease without requiring a complete lockdown of the population and shutdown of the economy. The classic reaction to detection of a highly lethal infectious disease is to quarantine a person when we realize they are infected because of the symptoms...
